Mining is the process of extracting useful materials from the earth. Some examples of substances that are mined include coal, gold, or iron ore.Iron ore is the material from which the metal iron is produced. The process of mining dates back to prehistoric times. Prehistoric people first mined flint, which was ideal for tools and weapons since it breaks into shards with sharp edges.

Iron ore . Total iron ore resources in India are about 28.52 billion tones (Bt). The total resources of hematite and magnetite in the country (as on 1.4.2010) are estimated at 17,882 Mt and 10,644 Mt 3. About 57% of iron ore production comes in the form of fines (including concentrates) during course of mining operations itself.
